SPECIFICATION forming part of Letters Patent No. 699,377, datedMay 6, 1902.

Application filed April 5, 190]..

T0 all whom it may concern:

U Be it known that I, FREDERICK F. FIELD, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Faucets, of which the following is a speciiication.

This invention has reference to `an improvement in faucets; and it consists in the peculiar and novel construction and the combination of parts more fully set forth hereinafter.

The invention is particularly adapted for faucets connected with high-pressure Waterservice, in which the valve is subjected to the blows of the Water-hammer and to excessive wear;

The object of the invention is to protect the valve against this excessive wear.

Figure lis a vertical sectional view of my improved faucet, showing the valve in the open position. Fig. 2 is a side View of the valvechamber. Fig. 3 is a side view of the adjustable stop by which the end of the valve-cham- Fig. 4 is a side view of the an enlarged chamber into Which the Water eli-- tering under pressure rushes and from which the water is discharged through the outletduct a3. The chamber a2 has the internallyscrew-threaded boss cui and on the opposite side the eXternally-screw-threaded nipple a5, the annular edge of which forms the valveseat a. The tubular sleeve c is secured by screwthread engagement with the nipple as and forms the valve-chamber. The opposite end of the sleeve c is closed by the screwplug c2 in screw-thread engagement with the sleeve. The plug c2 is provided with the stop c3 and with a notch, so that by the use of a screw-driver the plug may be turned and the stop adjusted to the desired position to arrest the outward movement of the valve. The valveb is a cylindrical cup-shaped metal disk tting the interior with a loose sliding iit. The cup of the valve is lled with any suitable kind of packing, which is secured by the screw lj. When the valve b is closed, the valve-seat au bears on the packing in the valve-cup. The openings c c extend through serial racisme (remodel.) L

the wall of the sleeve c and form the Waterd passage from the exterior to the interior of the valve-chamber. These openings c c are disposed, in the preferred form shown in Fig. 2, spirally and in relation to the movement of the valve b so that when the valve is wide openthe openings c farthest from the valve-seat are covered by the valve, while the openings c near the valve-seat are uncovered. By this arrangement of the openings the valve is practically balanced until it passes the openings c c nearest the valve-seat, when the water forces it to the seat,

I do not wish to confine myself to the spiral arrangement of the openings c c', as this disposition may be changed without affecting the invention, the material or essential feature of which consists in perfor-ating the wall of the valve-chamber over which the valve moves with a series of openings.

The valve-stem b2 bears on the screw b' and is provided With the annular cup b3. The tubular post b4, secured by screw-thread engagement in the boss a, forms the sliding bearing for the valve-stem and fits the cup b3 with a loose sliding fit. By a loose sliding fit I mean a iit which while'it permits Water to pass into the cup b3 retards the outflow of the water from the cup and the seating of the valve. A suitable head or button b5 is secured to the valve-stem b2, by which the valve may be operated.

When in the use of a faucet a prolonged flow is desired, the curved lever d is pivoted at d to the case of the faucet, and I provide the lever with the pivoted latch cl2. When the valve is pushed inward into the open position, (shown in Fig. 1,) the lever d may be swung over the head b5 and secured by swinging the latch cl2 into engagement with the le ver. l/Vhen the lever CZ is released, the pressure on the valve acts to close the same automatically.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of an inlet-pipe, an outlet-pipe and a chamber connecting the two said pipes, a valve-casing arranged within the' inlet-pipe with its inner end closed and pro# vided with a valve-seat at its outer end and communicating with said chamber,- the walls IUD ' or openings communicating With said inletpipe and arranged in a plane or planes oblique to the axis of said casing and extending over an area about equal to the range of movement of the Valve, an imperforate valve moving Within said casing and having its periphery sliding over the said ports or openings in'the casing and its outer face acting upon the said valve-seat to close the passage at such point, the pressure of the fluid upon said valve serving to normally hold the valve closed 0n its seat, and means for pushing the valve from its seat to open the passage, said means being disconnected from said vaflve, substantially as and for the purpose set forth.

2. The combination of an inlet-pipe, an out'- let-pipe and a chamber connecting the two said pipes, a valve-Casin g arranged within the inlet-pipe with its inner end closed and provided with a valve-seat at'its outer end and communicating with said chamber, the walls of said valVe-casingbeingprovided with ports or openings communicating with saidinletpipe and arranged in a plane or plan es oblique to the axis of said casing and extending over an area about equal to the range of movement of the valve, an imperforate valve moving within said casing and having its periphery sliding over the said ports or openings in the casing and its outer face acting upon the said valve-seat to close the passage at such point, a valve-stem mounted through the wall of said chamber with its outer end projecting to the exterior thereof and its inner end acting upon the said valve to push it open but disconnected from said valve, substantially as and for the purpose set forth.

3. The combination of an inlet-pipe,an ontlet-pipe and a chamber connecting the two said pipes, a valve-casing arranged within the inlet-pipe with its inner end closed and provided -with a valve-seat at its outer end and communicating with said chamber, the walls of said valve casing being provided with ports or openings communicating with said inlet-pipe and arranged in a plane or planes oblique to the axis of said casing and extending over an area about equal to the range of movement of the valve, an imperforate valve moving Within said casing and having its periphery sliding over the said ports or openings in the casing and its outer face acting upon the said valve-seat to close the passage at such point, a reciprocating valve stem adapted to push upon the outer face of said valve to force it from its seat against the pressure of the fluid, the said Valve-stem being provided within said chamber with a liuid cushion which is supplied with fluid from said chamber to prevent the sudden closing of the valve on its seat, substantially as and for the purpose set forth.

4. In a faucet,the combination with a valveoperating stem provided with a cup and a stationary post in the cup, of the valve-seat a, the tubular sleeve c provided with a series of diagonally=arranged ports or openings c', the plug c2 in screw-thread engagement with the sleeve, the stop c3 and the valve b, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
